= 28.26 square meters

A sprinkler rotates thru 60° = 1/6 of a circle (360 / 6 = 60°)

so 
28.26 / 6 = 4.7

Write the equation of the line that has an x-intercept of -3 and passes through the point (-3, 7).
Marina86 [1]

Answer:

x=-3

Step-by-step explanation:

'x = -3', when graphed, passes through the point (-3,7) and (-3,0).

Since the line passes (-3,0), the x-intercept is -3.

(-3, 7) lies on the equation.

I have attached a picture of the graphed equation.

'x = -3' should be the correct answer.

what is 40% off of $712.00 please explain how you got your answer as if you were teaching me how to do it.
Vikentia [17]

Answer: $284.80

look when you are trying to find the percent of a number you need to turn the percent into a decimal then multiply the decimal by the number:

1st. 40% as a decimal is 0.40 because as a fraction 40% is 40/100 so that means that 1.00 is 100 and 0.40 is 40%

2nd. Next, you do 0.40 x 712.00 = or

712.00

x  0.40

______

$284.80

Hannah scored a total of 170 points on two math tests. The score of the first test was 6 points lower than the second test. How
tester [92]
Ok so in order to do this, you have to set up an equation. Let's make a=the score of the first test and b=the score of the second test. (You can choose different variables, it doesn't matter.) It says the sum of the two equals 170. So, a+b=170. It also says that the score of the first was 6 less than the second. This can be shown as a=b-6. Now you can plug this in for a in your original equation. It will look like:

(b-6)+b=170

You can solve for b.

2b-6=170
2b=176
b=88

Since you want a, plug into either equation for b. I'll use the second one.

a=88-6

So, a=82
